ABSTRACT
Background: Peritoneal carcinomatosis (PC) is a lethal regional progression in patients with colorectal cancer (CRC). Treatment with complete cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) achieves better local control than systemic palliative chemotherapy. Objectives: To assess the efficacy on the prognosis of CRS and HIPEC compared with CRS only and to identify possible clinicopathological factors associated with the recurrence of PC. Methods: The present retrospective study included all colorectal carcinoma cases with PC subjected to CRS with or without HIPC from January 2009 to June 2018 at the National Cancer Institute (NCI), Cairo University, Cairo, Egypt. The outcome is evaluated in terms of recurrence-free survival (RFS) and its predictors. Results: Out of the 61 patients, 45 patients (73.8%) underwent CRS plus HIPEC, and 16 (26.2%) underwent CRS alone. The 1-year RFS was 55.7%, with a median of 12 months. The risk factors for recurrence identified in the univariate analysis were T4 primary tumor, high-grade, positive lymphovascular invasion (LVI), positive extracapsular nodal spread, and patients treated with CRS only, without HIPEC. In the multivariate analysis, the independent risk factors for recurrence were high grade and patients treated with CRS only. Conclusion: T4 primary tumor, high grade, positive LVI, and positive extracapsular nodal spread seemed to be important predictors of recurrence following the treatment of PC. Our study also demonstrated that the addition of HIPEC to CRS improved the RFS. (AU)

AIM OF WORK: Robotics in surgery led to an improvement of visualization, a better handling of tissues and better suturing. This study aimed to document the first experience of the Egyptian National Cancer Institute (NCI) using the robot-assisted laparoscopic approach in radical hysterectomies for cervical cancer and to highlight observed advantages, disadvantages, morbidity and oncological outcomes. PATIENTS AND METHODS: Data of cases that had either early cervical cancer (stage IB-IIA1 with a tumor ≥2â¯cm) or locally advanced cervical cancer (Stage IIA2-IIB after chemo-radiotherapy) were collected prospectively. Study patients underwent robotic radical hysterectomies for their cervical cancers at the NCI, Cairo University, between January 1, 2015 and December 31, 2016. For each patient, duration of surgery, amount of blood loss, and intra-operative complications were recorded. Similarly, the duration of postoperative hospital-stay, analgesia used and post-operative gastrointestinal recovery were documented. Pathological assessment of safety margins and the lymph nodes number yield were also assessed. RESULTS: Twenty patients underwent robotic radical hysterectomy during the study period. Twelve cases had early cervical cancer while 8 suffered locally advanced disease. The mean procedure time was 319 (range 240-560) minutes; the mean blood loss was 309 (range 150-600) ml. Three cases had bladder injuries during their procedures. The median hospital stay was 6 (range 4-10) days. One case had a positive margin. The median of lymph nodes yield number was 15 (range 10-25). Follow-up ranged 9-31â¯months, with only one case developing local recurrence. CONCLUSION: Robotic radical hysterectomy is a feasible approach with a tolerable rate of complications.
